President Obama was recently spotted on the golf course with the Game Golf device.

So how does it work?

First, a small device is attached to the player's belt. Small dime-sized sensors are inserted to the top of the grip on each club. Prior to hitting a shot, the player taps the sensor on the end of the club against the belt-mounted unit. The system then records the length of the shot, the location of the shot/accuracy, and through that, aggregates different performance metrics that can illustrate the players tendencies, strengths, weaknesses, etc.

Game Golf also has an online network where users can interact with each other and even challenge each other on a list of available courses within the platform. So two or more golfers could compete with each other on the same courses, without ever playing together.
